A contractor diagnosing Central AC in Robertson County has to settle one question before anything else: what actually wore this part out. 16 severe weather events were recorded in Robertson County, Kentucky between 2015 and 2024. At that rate, severe weather lands here but does not define what every system has been running against season to season. Age, refrigerant charge, and how well the original install was executed are what a contractor finds written in a compressor or a failing contactor far more often than storm load is. A homeowner who hears 'weather damage' as the first explanation deserves a closer look at the equipment itself.
Ductwork in a house this old was put in for the equipment running in it decades back, and the contractors who open these systems find components that have been out of production for years. Half the homes in Robertson County, Kentucky were built in 1985 or earlier (2020-2024 ACS 5-year). When a repair call comes in, the part number matters more than the square footage. A contractor who can source what an older refrigerant-cycle system actually takes gets the job done; one who cannot is writing a replacement quote instead.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits on a pad beside the house and holds the compressor, the condenser coil, and the fan that pushes heat outside. When the system runs but does not cool, or does not run at all, this is where a contractor looks first. A failed compressor, a refrigerant leak at the coil, or a seized fan motor will each show up here.
Inside the house, the air handler holds the evaporator coil and the blower that pulls return air across it. The refrigerant line set connects the two units and carries refrigerant between them. A clogged coil, a weak blower motor, or a leak in the line set can each stop the system from doing its job, so a contractor works through all of it.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to this particular house.

Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
